514813-35-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 514813-35-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,4,8,1 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 514813-35:
(8*5)+(7*1)+(6*4)+(5*8)+(4*1)+(3*3)+(2*3)+(1*5)=135
135 % 10 = 5
So 514813-35-5 is a valid CAS Registry Number.

Synthesis of the benz[a]anthraquinone core of angucyclinone antibiotics
Kalogerakis, Aris,Groth, Ulrich
, p. 843 - 844 (2007/10/03)
A general method for the synthesis of benz[a]anthraquinones is reported. The key step is a catalytic cobalt-mediated [2+2+2]-cycloaddition of a triyne, which affords an angularly substituted tetracycle. Oxidation of this core gives the typical structure o
